  1. RUSF: Ready-to-use Supplementary Food
  2. Costs have been rounded to the nearest euro.
  3. * Estimates for diarrhea incidence in the control area are given a wider range due to higher loss to follow-up on monthly incidence outcomes in the control area, and resulting higher uncertainty in these estimates.
  4. Ç‚ Component costs are only used in univariate sensitivity analysis.
